Target concentration % → stock + water
Bland en desinfektions-brugsopløsning: ml stamopløsning = liter · 1000 · (mål-% ÷ stam-%); resten er vand. Beregneren tjekker målet mod de anbefalede intervaller fra SSI/Miljøstyrelsen: alkohol 70–85 %, klor 0,1 % (1000 ppm), kvat. ammonium 0,5–5 %. Bemærk: for alkohol blandes ethanol og vand ikke additivt (volumenkontraktion ~3–4 %), så vandmængden er kun vejledende. Følg altid produktets egen brugsanvisning og indvirkningstid.
